Cinder 13.x releases are OpenStack Rocky, and the upper-constraints for 
Rocky [1] says oslo.messaging===8.1.2, so there should be no need to 
backport this fix.

Are you trying to run the unit tests when you see this? When I run tox 
on stable/rocky, it installs 8.1.2 as one of the dependencies, although, 
to be honest, I'm really not sure how tox knows that that's the right 

Or are you trying to run Cinder from Rocky with newer oslo.messaging, 
and getting the same symptom as the unit test failures in that bug, when 
running the cinder services? If so, a) it's an unsupported combination 
(I believe) and b) you'd (at least) need to update your configuration to 
remove use of that deprecated rpc_backend option.
